YARN-GUIDE SUPPORT FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 2 60,360, dated July 4,1882. Application filed April 3, 1882. (No model.)

' To all whom it may camera:

Be it known that I, JOHN BIRKENHEAD, of Mansfield, in the county ofBristol, of the State of Massachusetts, have invented a new and usefulImprovement in the Yarn-Guide Supports for Bing Spinning Frames; and Ido hereby declare the same to be described in the followingspecification and represented in the accompanying drawing, whichexhibits a transverse section of the upper part of a ringspinning frameprovided with my invention, the nature of which is defined in the claimhereinafter presented.

In practice it has been found objectionable to sustain the yarn-guiderail by vertical guides, and to apply to such rail or its supports oneor more counterbalancing-springs, in manner as represented and describedin Letters Patent N 0. 214,749, granted to me on April 29, 1879, for thefriction attendant on the upward movement of the yaruguide and itssupports has proved an obstacle to the starting thereof by the ring-railacting against the arm extending from the supporting standard orstandards of the yarn-guide, the result of such obstacle being a more orless uneven laying of the yarn on the bobbin. My present improvement isto avoid this difficulty, and in carrying it out I combine with themachineframe and each of the threadguide boards and itssustaining-standards, provided with adjustable arms to extend from itover the ring-rail, counterbalancing-springs and pivotedsupporting-arms, the said arms being extended from the guide-railstandards across the machine-frame, and pivoted at their rear partsthereto, and supported by the counterbalancing-springs suspended fromthe creel. At its ends the thread-guide board may be furnished withfriction-wheels to bear against the next adjacent vertical ends of theframe.

In the drawing a thread-guide is shown at b and its. carrying-board atB, the latter being supported near each of its ends by a standard, (3,from which there projects over the ring-rail E an arm, D, applied tothe-standard so as to be adjustable vertically thereon. The lower partof the standard has a tubular projection, 0, provided with a set-screw,61, such projection being to receive in its bore the supporting-arm G,which extends across the frame A in manneras shown, and is pivoted toit,as represented at H.

G is one of the supporting-bars of the opp'osite yarn-guide board. Bymeans of the tubular projection c and its set-screw d the standard 0 maybe fastened to the arm G, and be adjusted-thereon, so as to bring theguide-board B at its proper distance from the front portion, 6, of theframe A,'there being fixed to the said portioue a rest, f, to receiveand sustain the yarn-guide board B when at its lowest position. a

Each yarn-guide board is to have to each of its supporting-standards 0an arm, G, and there should be over such arm a counterbalancin g spiralspring, I, which, suspended from the creel K, should be connected withthe arm by suitable means-as, forinstance, a cord, 9. The springs I,when the guide-board B is upon the rest or rests f, should operate witha lifting-power sufficient to or about to counterbalance the weight ofthe arms Gr, and the threadguides, the guide-board B, its standards Oand their arms D, and the tubes 0 and their screws d, in order that onthe ringrail rising and impinging against the arms 1) itshall meetwithlittle, if any, resistance to effect the starting upward of theguide-board.

In the place of the spring I and cord g to each of the arms G, Isometimes make use of a cord going about a pulley, and fixed at one endto the arm and at the other to a weight, the arms and their adjunctsbeing counterbalanced by the weights. The hingepiu of the arm H, Iusually arrange at an altitude which shall be in a horizontal planesituated midway of the rise of the lower face of the board B above therest f.

I would remark that I do not herein claim the mode represented in mypatent aforesaid of sustaining a yarn-guide board andcounterbalancing-springs with it.

. What I claim as my present invention is as follows, viz:

The combination, with the frame of a ringspinning machine, and with eachof its yarnguide boards and its supporting standards, of pivoted armsand counterbalancin g-sprin gs, arranged and applied substantially asset forth, the standards being provided with adjustable arms to extendfrom them to and over the ring-rail, as represented.

JOHN BIRKEN HEAD.
